At least two people have been killed after four earthquakes struck within an hour's time near the northern coast of Papua in Indonesia on Wednesday. According to Papua police spokesman Wachyono, two people dead and 20 houses were collapsed on the island of Yapen.There were also reports of fires burning, he added. A quake with a magnitude of 6.4 struck at 12:06 p.m. local time, followed by a more powerful of 7.0 magnitude 10 minutes later. The U.S. Geological Survey reported that within the next 40 minutes, a 5.1 magnitude quake also rattled the region, along with a magnitude of 6.2 quake. The epicenters of the earthquakes were clustered within 50 kilometers of each other.People ran out of their houses and headed for higher ground in fear of a tsunami. A tsunami watch that was issued by the Indonesian Meteorological Agency was later lifted. In 2004, a 9.1-magnitude underwater earthquake struck off the coast of Sumatra, triggering a tsunami that killed more than 200,000 people in 14 countries.
